To. lrALL Wn'oM IT MAY consensi: Be it known that We, HORACE PALMER and ASA N, CASE, of Kingsville, in the c'ilnty of Ashtabula, and

Stateof Ohio, ,have inventeda new end useful Improvement in Double-Trees, Snc.; .ajnd We do hereby declnre that the following is a full, clear, and exact description theref,'which will enable others skilled in the art to malte and use the saine, reference `being hadto the accompanying drawings, forming part of this specification, in whichy l A i i v 4 The figure is a top View ofv a donble-tree to Vwhich our improvcmenthas been attached. part being broken away to show the construction. y 4' l Similar letters of reference indicate like parts.

Our invention has for its object to furnish a simple attachment for double-trees; whitlie-trees, neek-yokes, tcn, where the power is applied tothe ends. of n. Woudenber, and the resistance is sustained at its centre, so as to greatly strengthen said bar, without materially increasing its Weight.' 4

It consists in the combination of'an iron brace-rod, Veye-bolt, and adjusting-nut, with the wooden bar, as hereinafter more fully described. i

4 A represents the wooden bar of a double-tree, to which the clevises B and socket C for the hammer-pin are attached in the ordinary menner. -V V I D is the strengthening-rod or brace, which runs along the rear side of the bnr A.' l

The ends of-the rod Dare bent forward at right angles, haveeyes or holes formed in them, and enter sockets formed in the ends of the wooden ber A, to receive-them in such positionsthnt therclevis-pins may pass through the said eyes or holes, and sec-nre the rodor brace D in place. v

` E is an eye-bolt, which enters a. hole or socket formed in the regir side of the central part of the bar A, to receive it, and through the eye of which passes the brace-rodD. v l

F is a nut screwing upon the eye-bolt E, and which rests against the rear side of tho wooden bar A, so that.v

by turning the said nut F in one or tigeothex direction, the Enid rod D maybe strained more or less tightly, es may be desired;

In'the case of neck-yokes, whiilie-trces, and, double-trees, where the resistance is sustained by a tonguel ring, eye, or staple, upon the same side of the bar A with the brace-rod D, two eye-bolts E, or their equivolent, shonld bensed, one being placed upon each side of said ring, eye, or staple.

By this` cohstrncton the strength of the wooden lbar A is so materially increased by the rod D,.tha.t the' seid wooden A may be mede much lighter than would otherwise be possible, While still furnishing the necessary strength. p a

Hnvingtlius described our invention, we claim es new, and desire to sc cnre by Letters Patent-- The brace-rod D, whose ends enter recesses in'the rear edge of the wooden her A, and are connected therein to the cleviscs B, when said rod is adjusted nearer to or further from the bar by the eye-bolt E, embracing its l l HORACE PALMER, 7 ASA N.
